What parallel does raskolnikov create to his own situation, to sonia understand his actions? what’s the basic error in this parallel?

Explained below.

Explanation:

Rask's parallel is by asking Sonia if she had rather have luzhin live and go on doing wicked things or have Katerina die. The basic error in this is that Sonia is religious and does not believe, she can depict who is to live or who is to die. Sonia does not know the divine providence of the great almighty god.

clarify customers’ doubts only when asked.

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
